T0 all whom it may concern.'

' Be it known that l, S'rouiioxr Jossniiiir, a citizen 'oi'. the United States, residingr at Atlantic, in the county of Norfolk, in the State of Massachusetts, have invented an ini- .provement in Fountain-Pens, of which the following isa specification.

'This invention relates to that class oi fountainpens iii which an expansible rubber' sack is provided within the barrel, and mechanical'means is provided in connection therewith for collapsing the saine; and, more particularly, to that particular type oit fountain pen in which a presser plateis'arranged to engage the sack throughout substantially its entire length, and lever is pivotally connected to the pen barrel in position to press the plate against the sacl` to collapse the saine, so that when the sack is permitted to expand, it will be filled with the liquid in which the pen section has been dipped.

Prior to my invention, variousdevices ot the above-described character have been pro duced, but said devices have. so far as l am aware, been open to certain objections, some of the more important of which have been diiiiculty in operation, unreliability of the locking means for .the operating lever, unsightly or inconvenient projections, and cessive cost of manufacture.

. The objects of iny invention are to provide a fountain pen, of the character-above referred to, in which the lever operating means is arranged to permit easy and convenient compression of the sack; and in which a. convenient and effective means for locking said operating means is provided. Further, to provide a construction and arrangement which Will enable the production of a tountain lpen which has a smooth, continuous surface throughout the length of the pen barrel,

so that it Will have substantially the same ap-y pearance as an ordinary fountain pen, un-

provided with mechanical means for eol-r lapsing the sack, and which is of simple and durable construction, so that it is unlikely to get out of order, and may be manufactured at a reasonable cost. l accomplish these olojects by the means shown inthe accompan3-- ing drawing, in which Figure l is a. side elevation of a fountain pen embodying my invention.v Figs. 2 and 3 are central longitudinal sectional views thereof, showing. the operating parts' in difin its nonnal or ino; era.- i

ferent positions. Fig. 4 is a detail view of the presser plate and its supporting means. Fig. 5 is a'cross-sectional view, on an enlarged scale, taken at the line 5 5 of Fig. 4. Fig. 6 is a similar view, taken at the line 6 6, Fig. 2. Fig. 7 is a plan view, showing a slightly modified ormof my invention. Fig is an enlarged sectional view. taken at the line 8-8, Fig. 7 Y

As shown in the drawing, the barrel a has the usual pen section Z) mounted therein, and a. rubber 'sack c is provided, which is arranged in the barrel, and .connected to a reduced portion on the 'inner end of the pen section. I

' A presser plate l is arranged to. extendl longitudinally of the rubber sack` through out substantially7 the entire length thereof,

said presser plate being connected to a springv 'arm e, whii'th'is, in` turn, connected to a metal split collar f, the latter being arranged closed end oi" the barrel. and partly across' the end wall thereof, and an operating lever I is mounted to vini?, in said slot a', about a pivot Ft, located the lever, und such a posi on that the ei;- terior surface of the lever is 1flush with the surface oiE the pen bari *when the lever is e position..

r1Ehe lever pivot is arranged to provide a short, or presser-plate-engaging-arm, and a. long, or operatingarin, the end-portion of which is provided with an oi'ij'set portion g, which is adapted to be received by the slot in .the end wall of the barrel, and from the end o which a sorew-threaded tip portion g2 is arranged to extend beyondthe end of the barrel, and in 'central alinornent there- `with, when the lever is' in its normal, or inoperative position..` A cap-nut i is Athreaded on said tip-portion g2, and is adapted .to-be screwed thereon against the end oi the barn barrel intermediate' rel,lbeing constructed to. forni a continuation of the tapering end portion thereof, and provide a suitable tip end therefor. Said' nut may be made oic metal, to provide an ornamentalltip, or of the sameinaterial as thebarrel, usually hard rubber, and, when made of the latter, will be preferably provided with an internal bushing y'in which ico the threads are formed. The tip end ofthe the necessary extent, and the lever g isI swungV outwardly, to cause its short varm to force in the presser plate, and collapsethe sack, as shown 1n Flg. 3, so that,I when the leverls swung'back to lts normal position,

the expansive force of the slack will causev the ink tobe drawn' therein -in the usual manner. ',Ihe nut i will then be. screwed againstthe endofthe barrel again, to lock the lever in its normal position. During the operation of the lever, the nut i provides a convenient handle, or means for grasping -it With the lingers.

form of my invention, in which, instead of arranging the pivotv li directly on the hard rubber of thebarrel, a metal band m is provided Vto receive the same,.which is arranged about the4 pen barrel, flush with they surface thereof, said band being also made to serve for ornamental purposes, if desired."

l. In combination with lthe barrel' of a fountain pen having a collapsible sack Figs.` 7 and' Sshovv a slightly modifiedy therein, a presser-plate arranged to engage said sack, a lever pivotally mounted in said barrel and arranged' to-engage'sald plate to collapsethe sack when swung from its normal position, and a nut threaded on the end of said lever and arranged to be screwed into locking engagement with the end yof the barrel, to lock the lever'in inoperativel position.

2. In combination with a fountain'v pen.

barrel having a longitudinall slot extending y continuously from an intermediate point in its side wall into the -end'vva-ll thereof, a.

lever pivotally mounted in said slot' and having one arm thereof provided'with an offset p'ortion, arranged to extend into the slot- 50 ted portion of said end Wall, and a threaded extension, projecting beyond saidend Wall of the barrel, a nut'. threaded on said extension and' adapted'to' be screwed against said end wall, to lock said lever in'inoperative v5t position, and ya collapsible sack in the barrel having a presser-plate arranged to be engaged by the opposite arm of said lever.

3. In combination with a fountain-pen barrel having a slot in its Wallextending',

longitudinal-1y thereof from its closed'- end, a lever pivotally connected to the barrelfto yswing in said slot, and, in the normal'position thereof, to .lie With Aits outer surface flushwith the surface of the barrel, .one arm ,of said lever having a threadedend-portion extending beyond the end :of the barrel-in central alinement thereWith,"When the lever is in said normal'4 position, a nut 'threaded on said end-portion', adapted-to be clamped '70' againstthe end of the barrelto lock said `lever in said position, and constructed vto `prov-ide a continuous `surface withy the ad- ,jacent portionofv thebarrel, and a collapsible sack in the' barrel'having a presser-plate 75 arranged to be engaged by the opposite-arm of the lever.

In testimony whereof, I have signed my j yname to this speciiication.v
